In the technological processes of oil and gas wells construction, a variety of general-purpose inorganic chemical reagents are used. The ingress of these reagents into the body of drilling enterprises employees together with the inhaled air, ingested food (through the pores and mucous membrane) is currently not sufficiently studied. The work investigated the effect of the Brucite drilling reagent on the lung tissue of rats of the non-linear albino line. With the inhalation of the Brucite drilling reagent to rats, the dystrophic processes were observed in their lungs, which were accompanied by the development of chronic inflammation and an acute macrophage reaction. There was a significant increase in the size of perivascular infiltrates compared to the control (13370 ± 248.6) μm2) with 14-day administration of particles of the Brucite drilling reagent — (14867.21 ± 369.29) μm2, with 30-day administration — 15853, 87 ± 126.57. Also, morphometric analysis showed a significant decrease in the area of alveolar space, and the area of medium-caliber bronchus. In the lungs, the formation of many airless areas was noted, alternating with emphysematous — altered, the severity of which increased with the duration of exposure to the drilling reagent. The consequence of work with Brucite drilling reagent of the drilling enterprises employees can be professional, acute, and chronic diseases of the lungs, as well as specific sensitization of the body caused by the exposure to dust particles. In the future, it is planned to conduct a statistical analysis of the incidence rates with temporary disability, occupational diseases, and occupational poisoning among the employees in contact with the Brucite drilling reagent, and the development of efficient measures to reduce the harmful effects of the Brucite drilling reagent on the certain categories of specialists at the drilling enterprises.

In connection with urbanization, the study of the influence of atmospheric pollution on the health of the population is an urgent task. The study of the respiratory system is of particular importance, since the respiratory organs are exposed to the harmful effects of pollutants in the first place. However, the influence of harmful substances on the bronchopulmonary system in the prenosological period has not been sufficiently studied, since the functional state of the body is more sensitive to the effects of environmental factors than the incidence rates.

All shampoos contain various harmful components that accumulate in the body, which can harm human health in general. They can cause allergies, provoke aging, lead to nervous disorders and cardiovascular disease. But, despite this, these substances can not be excluded from the composition of modern shampoos, as without this cosmetics will lose their properties. Choosing the right shampoo will help reduce the risk of harmful effects, but you need to know how it can adversely affect the health of an ingredient. The result is the recommended lists of specific shampoos that take into account all these aspects. Consumers who care about their health should be directly interested in such lists. The aim is to identify the safest groups of shampoos in terms of their content of substances dangerous to human health. The object of personal hygiene products is shampoos (25 items). The subject of the study is the description of the safest groups of shampoos for consumers, taking into account their price and subjective assessment of consumers. The initial data was information about the composition of each of the shampoos and toilet soaps, specified by the manufacturer on the product packaging of each tested hygienic product. During the study, comparative-descriptive, graphical, and statistical (method of K-means cluster analysis) methods of processing and providing information were used. The results of the work are of direct practical importance, as they represent a direct recommendation for the consumer, which is the need to choose personal hygiene products (shampoo) among the proposed lists of the safest samples with the lowest price and best consumer properties.

Oil and gas installations both onshore as well as offshore are often built in modules and components on a different location than where those facilities are commissioned. Although stress and fatigue damage have proven to be significant on these structures during ocean transport, ocean transportation is often not adequately accounted for during design. Prior to arrival on its final destination, constructions are exposed to severe motions when carried on a modules carrier, a general purpose vessel or towed by 1 or more ocean tugs. The authors argue that calculations on the significance and effect of these motions should be based on proper motion response calculations instead of currently used ‘rules of thumb’. Especially regarding the continuing growth of the size of these carriers and the weight of the structures which both increase the negative effect of sea behavior and affects the loads on the constructions. This article aims to explain the importance of design for transport during the design-phase of these onshore and offshore structures. A distinction is made between structures transported aboard a barge, semi-submersible or general purpose vessel and floating structures transported through a ‘wet-tow’ operation.

Nowadays it is difficult to imagine the food industry without the use of various food additives, such as flavors, flavor enhancers, emulsifiers, dyes and other food mixtures, which make food both tasty looking and delicious. Vanilla is found in many essential oils, particularly in the pods of Vanilla planifolia and Vanilla pompona. Natural extract of the most popular fragrance in the world is very expensive and is not available in stores. Therefore, in order to meet the needs of the food industry, the artificial Vanillin flavor is made. The negative effect of synthetic vanillin is quite obvious, because it contains chemical compounds harmful to health. The most dangerous component of this fragrance is coumarine. Since this mixture is a carcinogen, it can ruin the liver. In addition, imitation of natural vanillin does not contain the salubrious components present in the authentic product. Taking into consideration the fact that the use of synthetic “Vanillin” flavor is widely used by the food industry and the harmful effects on the body have not been properly studied, there is a need to study the effect of “Vanillin” flavor on the physiological and reproductive functions of organisms. As the object of study, Drosophila melanogaster of lines Normal, vestigial, and white have been used, their descendants have been counted. Aiming to study the genotoxic effects of the liquid synthetic “Vanillin” flavor, it was added to a standard nutrient medium (50 ml) at the recommended dose (0.25 mg), a dose of 10-fold (2.5 mg) and a dose of 20-fold (5 mg) The medium was dispensed into test tubes, each of them containing 14 Drosophila melanogaster flies (6 females and 8 males). The quantity of each line has been calculated on the 8th, 12th and 16th days. It was experimentally determined that the use of the recommended dose of flavoring as well as the doses increased by 10 and 20 times, contributed to the increase in the number of Normal line compared to the control group by 10.98%, 9.89% and 5.92% respectively. An increase in number was also observed in the vestigial line. The white line showed a decrease in offspring by 21.3% and 11.1%, respectively, after the addition of the recommended dose and the dose increased by 10 times. However, the addition of 10-fold increased dose resulted in an increase by 137%.

Any economic activity carried out by an organization, can generate a wide range of environmental implications. Particularly important, must be considered the activities that have a significant negative effect on the environment, meaning those which pollute. Being known the harmful effects of pollution on the human health, the paper presents two models of utmost importance, one of the material environment-economy interactions balance and the other of the material flows between environmental factors and socio-economic activities. The study of these models enable specific conditions that must be satisfied for the economic processes friendly coexist to the environment for long term, meaning to have a minimal impact in that the residues resulting from the economic activity of the organization to be as less harmful to the environment.

AbstractThis paper deals with the mathematical modeling of atherosclerosis based on a novel hypothesis proposed by a surgeon, Prof. Dr. Axel Haverich (Circulation 135(3):205–207, 2017). Atherosclerosis is referred as the thickening of the artery walls. Currently, there are two schools of thoughts for explaining the root of such phenomenon: thickening due to substance deposition and thickening as a result of inflammatory overgrowth. The hypothesis favored here is the second paradigm stating that the atherosclerosis is nothing else than the inflammatory response of of the wall tissues as a result of disruption in wall nourishment. It is known that a network of capillaries called vasa vasorum (VV) accounts for the nourishment of the wall in addition to the natural diffusion of nutrient from the blood passing through the lumen. Disruption of nutrient flow to the wall tissues may take place due to the occlusion of vasa vasorums with viruses, bacteria and very fine dust particles such as air pollutants referred to as PM 2.5. They can enter the body through the respiratory system at the first place and then reach the circulatory system. Hence in the new hypothesis, the root of atherosclerotic vessel is perceived as the malfunction of microvessels that nourish the vessel. A large number of clinical observation support this hypothesis. Recently and highly related to this work, and after the COVID-19 pandemic, one of the most prevalent disease in the lungs are attributed to the atherosclerotic pulmonary arteries, see Boyle and Haverich (Eur J Cardio Thorac Surg 58(6):1109–1110, 2020). In this work, a general framework is developed based on a multiphysics mathematical model to capture the wall deformation, nutrient availability and the inflammatory response. For the mechanical response an anisotropic constitutive relation is invoked in order to account for the presence of collagen fibers in the artery wall. A diffusion–reaction equation governs the transport of the nutrient within the wall. The inflammation (overgrowth) is described using a phase-field type equation with a double well potential which captures a sharp interface between two regions of the tissues, namely the healthy and the overgrowing part. The kinematics of the growth is treated by classical multiplicative decomposition of the gradient deformation. The inflammation is represented by means of a phase-field variable. A novel driving mechanism for the phase field is proposed for modeling the progression of the pathology. The model is 3D and fully based on the continuum description of the problem. The numerical implementation is carried out using FEM. Predictions of the model are compared with the clinical observations. The versatility and applicability of the model and the numerical tool allow.

AbstractThe epidemic of the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has impacted worldwide with its infectious spread and mortality rate. Thousands of articles have been published to tackle this crisis and many of these have indicated that high air pollution levels may be a contributing factor to high outbreak rates of COVID-19. Atmospheric pollutants, indeed, producing oxidative stress, inflammation, immuno-unbalance, and systemic coagulation, may be a possible significant co-factor of further damage, rendering the body prone to infections by a variety of pathogens, including viruses. Spermatozoa are extremely responsive to prooxidative effects produced by environmental pollutants and may serve as a powerful alert that signals the extent that environmental pressure, in a specific area, is doing damage to humans. In order to improve our current knowledge on this topic, this review article summarizes the relevant current observations emphasizing the weight that environmental pollution has on the sensitivity of a given population to several diseases and how semen quality, may be a potential indicator of sensitivity for virus insults (including SARS-CoV-2) in high polluted areas, and help to predict the risk for harmful effects of the SARS-CoV-2 epidemic. In addition, this review focused on the potential routes of virus transmission that may represent a population health risk and also identified the areas of critical importance that require urgent research to assess and manage the COVID-19 outbreak.

Abstract Introduction Persistent Toxic Substances (PTS) are substances that are characterized by the cumulative effect at low doses inside the body. Exposure to PTS in pregnant and breastfeeding women, through food consumption, shows various harmful effects on the health of the mother, the fetus and the baby. The objective of this article is to analyze how pregnant and breastfeeding women perceive the presence of chemical substances in food and reflect on the accumulation, transmission and elimination of these substances. Methodology Descriptive and interpretive study under the qualitative research paradigm following a phenomenological and ethnographic perspective. As instruments to obtain the primary data we rely on 111 semi-structured interviews with pregnant and breastfeeding women, 4 focused ethnographies, 8 focus groups (63 women), 71 feeding diaries, 71 free listings. To encode the content of the speeches of pregnant and nursing women we rely on the N-Vivo 12 software. Results Pregnant and breastfeeding women are concerned about food quality controls. Women trust on local and seasonal foods such as fresh fruits and vegetables from non-extensive crops and close to their home. Foods that produce distrust in women are processed, packaged foods, red meat and large fish. The latter foods promote in women a perception of risk of contamination by chemical substances, manifesting a defenseless situation to maintain a diet without contaminants. Conclusions Pregnant and breastfeeding women in Spain have no information on the risk and danger of synthetic chemicals or PTS, with the exception of certain toxic substances such as mercury present in large fish. Women maintain a duality in their own care and that of the fetus or child. This circumstance implies that the women interviewed believe that PTS and synthetic chemicals may have different harmful effects on the mother and the degree of growth of the fetus and, subsequently, of the baby. Key messages Future mothers are worried about the type of product they eat, knowing that food influences healthy growth and development of the fetus. Pregnant and breastfeeding women often distrust “processed” or “industrial” foods, which they tend to associate with low quality and large amounts of additives and chemical substances.

The COVID-19 pandemic has put a hold on the Silent Mentor Programme (SMP); this pause has not only caused unprecedented challenges for the delivery of medical education but has forced changes in the programme ceremony sessions. We aimed to describe the psychological impact and experiences of family members of silent mentors during the COVID-19 pandemic using qualitative interviews. Many expressed feelings of remorse and unrest about the unprecedented delay of the SMP. The delay increased negative emotions particularly among some elderly family members; however, there was no prominent negative effect on their functional health and well-being. Several participants relayed the belief that the soul cannot rest until the body receives a proper burial while some worried about the deterioration of the physical condition of the mentors. In conclusion, findings provide insights into the importance of not overlooking the mental health implications of delaying the SMP in future outbreaks or crises.
